Wireless Charger Damaging phone?

Hi, I'm using my fast wireless samsung charger. I was told by someone that the magnetic field can damage your phone??? And with the new FAST wireless charger, the magnetic field is even stronger which enables the fast wireless charging. Can wireless chargers actually damage the phone?

P.S. I'm using it with my Note 5 (N9208 Taiwan Import). I have to use a travel adapter on the plug because taiwan plugs are 2-pin and UK plugs are 3-pin.
